nuke 3d – mdd possible or not?

hi, i’m creating object fracturing simulation, i can send the final simulation to nuke via .obj format as geometry sequence without any problem. Now i’m just curious… is it possible if i just import in the geometry source then apply the mdd deformer inside nuke? anyone know if there is any mdd importer available for nuke?

thanx.

slice tool

Hello guys!
Guess most of you have downloaded set of tutorials on thefoundry.co.uk. Is it possible use slice tool gizmo mentioned there http://www.thefoundry.co.uk/articles…ur-correction/ as nice colorized histogram? I really have no idea to what purposes it has two points.

spill supression algorithm help

Hi guys im researching digital keyers in nuke and am currently looking at spill suppression algorithms.

ive found that the basic principle of a spill removal operates on each pixel in the image:

if green > red
then clip green to red ( green = red )
else green = green

Does anybody have any suggestion on what nodes i would use to implement this algorithm. or better yet how to script this with python??

nice shadows

Confusing Transform Manipulators?

Hello,

Noob question. When having a script with tons of transform controls on multiple objects in a 2D setup, the manipulators tend to be very confusing on the screen with all of them looking the same and overlapping over each other etc. If I am not mistaken, double clicking on a transform node doesn’t automatically get it selected in the viewer. There are also no names or labels in the viewer. Is this just the way it’s done? Is there something I am missing to make this simpler? Thanks in advance for any help…

Nuke camera export scale issue

Hi,
I’m hoping someone can help me here…
So I’ve been using Nuke’s inbuilt CameraTracker a lot recently and love how quickly I can achieve a solid track on the majority of footage. However, getting that tracked camera (along with placement geometry) into a 3D app always seems to result in a miniature scene :confused:

So I’ll export the scene from Nuke as an FBX file using the ‘WriteGeo’ node. I then import that FBX file into Cinema4D or Houdini and bring in the cam, geometry and animation. The resulting scene is really tiny. I can drop in a standard sphere and have to scale it to around 1-5% of its original size, otherwise it engulfs the entire scene. It’s honestly like comparing a beachball to a golf ball (the latter being the scene).

Is this normal? Or is there a step I’m missing out, or an option I’m not selecting somewhere?

It’s driving me up the wall tbh 🙁
Any advice is greatly appreciated.

Thanks in advance.
